It's a crossroads, of sorts. To go left or to go right? Or perhaps, to stay and see if something happens to influence your decision? Either way, you feel it in your bones that your choice is one upon which the balance of your life temporarily teeters. You know that this could be the decision you regret for the rest of your life. Is uncertainty going to hold you back? It does for a moment, then a little bit longer while you try to make up your mind.
Did you cross that bridge to see what was on the other side? Was it better? Was it worse? Could you return from whence you came?
Did you grab life and let it lead you? Or did you let the last train pass you by?
